ROLLING GLASS.

SPECIFICATION forming part of Letters Patent No. 326,764, dated September 22, 1885.

Application filed May 11, 1895. (No model.)

To all whom it may concern.-

Be it known that we, FREDERICK MAsoN, of Ryhope Road, near Sunderland, England, smith, and JOHN CONQUEROR, of Hendon,

5 Sunderland, England, glass-maker, subjects of the Queen of Great Britain, have invented new or Improved Machinery for Rolling Glass, (for which we have made application for Letters Patent in Great Britain on the 3d day of October, 1884, No. 13,119, and in France on the 14th day of April, 1885, and in Belgium on the 15th day of April, 1885, and in Germany on the 18th day of April, 1885,) of which the following is a specification.

The rolling of glass into sheets has hitherto been effectedin the following manner: The molten glass is poured onto a flat horizontal iron table, on'which are placed near its sides adjustable and removable metal strips of a height equal to the thickness of the sheet of glass to be made. A heavy iron roller, the ends of which bear on the metal strips described, is passed over the molten glass, thereby spreading it on the table into a sheet of uniform thickness, the width of the sheet being regulated by adjustable guides propelled with the glass along the table. This, the ordinary method of manufacture, has the following disadvantages, namely: that the surface of the glass which has been in contact with the iron table is without brilliancy; a portion of one end of the sheet is waste, owing to the chilling effect of the first action of the roll 11 the first cost of the app and its use is attended pense.

Our invention has for its object to obviate these disadvantages; and it consists of machincry for rolling glass, which said machinery is constructed, arranged, and worked in the following manner: Ne mount on a portable frame a pair of smooth cylindrical adjustable iron rolls, one above the other. The axes of the 5 said rolls are horizontal, and are situated in a plane somewhat inclined to a vertical plane,

as hereinafter more particularly explained. The said rolls are geared together so as to rotate wit-h the same velocity in opposite directions. They are driven by hand or by pon the molten glass; aratus is considerable, with great currentextable and the Patented in England October 3, 1884, No.13,119.

same curvature as the upper part of the lower roll. This inclined plate has a breadth very nearly equal to the length of the rolls. The glass is received upon the lower roll, and by the motion of the said 10 forward and seized between the two rolls and delivered from between them onto the table hereinafter described. The upper roll is in advance of the lower roll-that is, the plane in clined, as hereinbefore pointed out, the upper part of the said plane being more distant from the front of'the rolls than the lower part. At the back of the rolls-that is,the side at which anything carried forward between the rolls is deliveredis an inclined table, adjustable and removable, of a width nearly equal to the length of the rolls, the upper edge of the said table being nearly in contact with the upper part of the lower roll. The edge of this plate has the curvature of the part of the roll with which it is nearly in contact.

The said machinery is used as follows: The rolls having been adjusted at the proper dis tance apart toproduce a sheet of glass of the 8 required thickness, and the guides having been placed on the front plate and adjusted to the required width, a suitable quantity of molten glass to produce a sheet of the size and thickness required is transferred from the meltingpot by means of a ladle or otherwise to the inclined plate in front of the rolls and deposited inside the guides. The molten glass runs from the inclined plate between the guides onto the lower roll, and the rolls being in motion in the required direction the said glass is carried between the two rolls and emerges at the back of the rolls in the form of a sheet of ess and bright on The molten glass, in its course 100 the required size and thickn both sides.

which is nearly in contact with and has the o0 wer roll is carried 65 which the axes of the rolls are situated is in- 70 down the inclined plate, may be directed and the rear parts of the stream shaped by a me tallic ferret or hoe-like instrument. The sheet is received on the inclined table at the back of the rolls, along which table it is conducted from the rolls,and is passed either directly to the annealing and piling kiln over the inclined table or passed from the inclined table over a cooling'plate or turn-table, and thence to the kiln, where, if necessary, it can be rubbed down. The sheet may be gently pulled forward with tongs,if necessary,to promote its motion on or over the inclined table. The table on which the sheet of glass is received may be horizontal instead of inclined. The rolls and their axes may be made hollow, for the purpose of permitting of the introduction of heating or cooling media, as may be found desirable, and the inclined plate on which the molten glass is placed on its transference from the meltingpot may be covered by a hood and provided on its under side with a casing or jacket, in which heating or cooling media may be introduced as required. The inclined or horizontal table on which the rolled glass is received may also be provided with a similar hood or jacket, or both, as may also the cooling-plate or turn-table aforesaid. The inclined plate on which the molten glass is deposited is provided with removable adj ustable metal guides to regulate the width of the sheet of glass to be made and to keep the molten glass within proper working limits. Rolls of different sizes may be employed in the manufacture of sheets of different sizes and thicknesses, and the machine may be supported on rollers or casters for facilitating its removal from place to place. One or both rolls may have on them any required pattern or patterns, the counterpart of which will be impressed on one or both sides of the sheet of glass by the rolling process.

Our invention is applicable to the manufacture of sheets of colored as well as uncolored glass, and also to the manufacture of opaque or semi-opaque sheets of glass, both white and colored.

Figure 1 of the accompanying drawings represents in end elevation, Fig. 2 in vertical section, and Fig. 3 in plan, a machine constructed according to our invention.

The same letters of reference indicate the same parts.

a and b are the rolls, of equal diameter, the axes a b of which work in bearings c d in the uprights or framing of the machine, the distance between the said rolls being regulated by the screws and hand-wheels e f. The said rolls are not immediately over one another, the upper roll being in. advance of the lower rollthat is, the axes of the said rolls are situated in a plane at right angles, or nearly so, to the face of the plate g,hereinafter referred to. One end of each of the axes a b carries a toothed wheel, a b which toothed wheels are geared together as seen in Fig. 1. The rolls a b are driven by means of the large hand-' wheels or x, the axis or spindle of which carries a pinion, y, which pinion gears with the toothed wheel 12 On giving motion to. the hand-wheels w as a slow motion is communicated through the pinion y and toothed wheels I) a to the rolls a b, which are thus made to rotate in opposite directions, their opposed parts traveling in the same direction, as indicated by the arrows in Fig. 2.

g is the inclined plate at'the front of the rolls, on which plate the molten glass to be rolled is poured, and h h are metal guides, between which the molten glass is poured and confined, and by which the width of the sheet to be produced is determined. These guides are removable,and their distance apart is regulated by screws and nuts at i t. The lower ends of the guides it have the same curvature as the parts of the rolls against which they are in contact, as represented in the drawings. By changing the distance of the said guides h it apart the width of the sheet of glass produced may be varied.

The inclination of the plate 9 may be adjusted in the following manner: The said plate 9 is supported by carriers Z Z, a rib, 9 on the under side of the plate 9 dropping into a recess in each of the carriers Z Z. The carriers Z Z are supported by the adjustable arms is k. The lower ends of these arms are jointed to the framing of the machine, and their upper ends engage by means of screws and screwnuts in one of a series of holes in the upper ends of the carriers Z Z. These holes are marked Z in Fig. 1. m is an inclined table at the back of the rolls, which table m is supported and adjusted in a way similar to that already described with reference to the plate 9.

It will be seen by an examination of Fig. 2 that the lower edge of the plate 9 and the up per edge of the table m are curved to fit that part of the lower roll to which they are presented and that the said lower edge of the plate 9 and the upper edge of the table m are either in actual contact or very nearly in contact with the roll I).

A quantity of molten glass sufficient to form a sheet of the size and thickness it is intended to manufacture is transferred from the melting-pot by means of a ladle or otherwise to the plate 9, on which it is poured between the guides h h. The said molten glass runs down the inclined plate g, its motion being regulated by the ferret hereinbefore referred to, until it reaches the rolls a b,when, being seized by the rotating rolls having motion in the direction indicated by the arrows in Fig. 2, it is made into a sheet having a thickness equal to the shortest distance between the rolls, and of a width somewhat greater than the distance between the guides h h. The sheet of glass thus formed travels down the inclined table m. The table m may be horizontal, although we prefer to give it the inclination represented, and

the sheet of glass as it passes from the rolls a b to the table m may be pulled gently forward with tongs, if necessary. The rolled sheet of glass may pass from the table in either directly to the annealing and piling kiln, or it may pass over a cooling plate or turn table, and thence to the annealing and piling kiln.

5 As the said cooling-plate and annealingkiln constitute no part of our invention,we do not think it necessary to describe the same.

The machine is supported upon rollers or wheels n n, by which it may be readily trans- IO ferred from place to place. Both sides of the sheet of glass produced when the rolls a b have a smooth cylindrical surface are very bright. \Vhen desired, one or both of the rolls may have any required pattern or patterns upon 15 it or them, the counterpart of which pattern or patterns will be produced on one or both sides of the sheet of glass rolled by the machine.

The machine may be driven by steam or 20 other power instead of by hand-power, as described, and represented in the drawings.

Having now particularly described and ascertained the nature of our said invention, and in what manner the same is to be per- 25 formed, we declare that what we claim is of new or improved machinery for rolling glass- 1. The combination of the pair of cylindrical rolls, the inclined plate in front of said rolls, and the laterally adjustable guides located in front of the rolls and over the in- 0 clined plate, substantially as and for the purposes described.
